System specs are in the signature.  I have a APC 1300 VA/780W UPS.  The only thing plugged into it are the computer, my Modem, and a small 4 port Switch.  When running Timespy at 120% power, max temp set to 93, and 150 on the core, the UPS starts squealing.  Checking the draw on the Unit and it shows between 790 to 840 watts, a bit too much.  I of course don't plan to run with these settings, and a benchmark is an extreme case of course, but seeing how I want to get 2 Hybrid kits for the cards, I want to make sure I have some headroom to spare.
 
Does anyone have any recommendations?  I don't really want to get one of these gigantic units that cost 800 bucks.  The APC 1500 VA can handle 900 watts, but even that seems to close for comfort?
 
Thanks.

    I'm using one with a 15 To 20 amp adapter. It's been working for 2 years now to great effect with my main rig (modrigs to the left) and just the past two days with a new AVR that beats the snot out of my old Sony AIO combo.

    400 dollars??? Holy Benjamins!!
    I did talk to EVGA and they said that 2 Hybrid Kits would add about 36 watts of additional draw.  I guess as long as I don't overclock the last ounce of performance out of them and don't spend all day benchmarking, I should be ok with my current unit.  I played some Witcher 3 and the draw was around 680, so that's not bad.  Going to try some other games later to get a better general idea.
     
    Thanks for the suggestions gentlemen!

    From personal experience (and many APC whitepapers). At least 10% stronger (Watts) UPS than PSU installed inside PC (if one). Unfortunately big units are quite required when you can draw close to 1kW. There is no way around numbers and UPS efficiency.
     
    Also you need to answer yourself one question. Do you wan't to keep system running for a while while power is out or shut-own it immediately. If first then you need good 50% more power. If the latter you can just cut it close, but its far from optimal in case of power outage while your system is drawing peak power - also from experience you lose about 25% of charge the moment PSU switch to batteries and weaker the unit/batteries MORE you'll lose during initial switch. Sometimes even 30 sec is not enough to close everything in proper order and it does not include servers and such.
     
    I prefer to run system at least for a while (give or take 5-10 minutes) before deciding on shutdown. Look at this from perspective that batteries which never work under load degrade just as fast as batteries running under load. My main system is hooked up to 3000VA Cyberpower (and whatever acronyms and random string on characters) with 1200W PSU. Not running SLI, but I need some work time on battery because it's my working machine and sometimes I have to finish something before shutdown.
     
    First thing I always do when power is out is to immediately cut number crunching. In idle [2D] mode system can technically run for good 40-50 minutes, but I never strain it to the brink.

    That is the one I use for my rig.  It is important to get a UPS that does a pure sine wave output as this mimics AC power.  Otherwise simulated sine wave can cause issues with the computer power supply both in efficient  and believe it or not make your PSU loud.

    You'll need something in the 1000w range to be safe.  I'm looking at the APC SMT1500 desktop or rack-mount(converted to tower).  It is $461, but most 1000w UPS is in the same price range.  I think APC/Sneider private labels a lot of models since they look very similar.  The nice thing about these units is they usually have more battery capacity than the cheaper $130-$190 1500va models.  Local rates for NP7 battery replacements is around $28/each and the cheaper units take (2) every 3-4 years.  The 1000w-1200w usually takes (4) batteries.  Anything with higher current and you'll need 20a electrical outlets.
     
    Basically, don't get caught up in the VA specs, use the watt capacity.  I just installed my ti FE SLI last night and peak overload my APC Back-UPS XS 1500va, 865w.  The UPS display peaked at 931w during Firestrike Extreme using +160/+500 overclocking.  UPS was spiking over 100%, but luckily, nothing sustained.  I only have the tower on this unit.  All my other devices/hardware are on a second APC.  When I have more time tonight, I'll use a Fluke clamp and check the load, but don't expect a big difference.  They are usually in the ballpark regarding current readings.
     
    Thinking Furmark would trigger overload protection and UPS will shutdown.

    Yep that CP 1500VA/1050 Watts, Pure Sine Wave UPS system Covers it all Now.
     
    The APC 1500VA Models only provide 865 Watts (Simulated Sine Wave) Will Shut Down @ 920 Watts Hard.

    Too bad that vendor doesn't ship any UPS to Hawaii.  Hit or miss for many items.  I'm still looking for a competitively priced 1000w unit with shipping factored in...  My non-gaming co-workers have a hard time comprehending my personal computer hardware draws 9 amps.

    Amazon Prime will not ship this to you in Hawaii?

    Hawaii and Alaska are foreign countries to retailers....  Seriously tho, we incur much higher shipping costs so Prime has exclusions on pricing and some items just don't ship.  So far; BB, Amazon Prime, CDW, and NewEgg(Premier) have the better shipping policies with some limitations.
     
    I don't qualify for the EVGA extended warranty since advanced RMA excludes outside of the continental US.  I was willing to pay more, but the corporate policies didn't allow it.
     
    That being said, I would hate to buy a UPS from Amazon since returning DoA sucks on large items.  I don't need to pack things nicely if I return to local BB, even if I buy on BB.com

    Our Prime, or Hawaii's prime, is also not 2 day shipping, we get 3-7 day standard shipping as our prime shipping.
    Not to mention Hawaii is now being taxed by amazon as well at the start of this month.
    A lot of battery type of devices, amazon nor 3rd party sellers, will not, or no longer ship to Hawaii, I'm guessing it having to do with worries over the whole Note phone fiasco.

    Go to costco.  They carry some there that are not bad and they tend to me reasonable price in HI.

    Need to go to a specialized reseller for SMB/Enterprise level UPS like APC SMT or SMX series.  Luckily, BB and CDW carries these.  APC SMT1500(1000w) is sufficient for some growth with my system.  I can't justify the cost of SMX1500(1200w).  Graybar, Anixter, and CSC charge a lot for shipping and usually have tiered pricing.  Non-corporate purchases are usually priced the highest.
     
    No way around it.  Consumer grade UPS is not good enough and you get what you pay for...

    I did dot catch the Location: Texas, USA, must be a long horn then.
    My last recall of power in Texas was every time an electric storm came in out went the power.

    I guess I will be saving my pennies for those high end ones.  I tried one more game, the Tomb Raider reboot which has pretty damn close to 99% GPU utilization on both cards the whole time and it stayed in the 690-710W range.  I am just wondering how the Hybrid kits will actually affect power draw, it really is only around 36 Watts then that should be ok. 
     
    As far as the battery part goes, all I want to do on battery power is shut the computer down as soon as the power goes out, I don't need to have it running to finish anything.  If I read one of the above comments correctly, these APC units have a hard shut off point at a certain power draw, is that correct?

    I have a 1080 Ti SLI set up, with i7 6850@ 4.2 ghz, EVGA x99 FTW k, 64gb Ram and 1000w EVGA supernova PS and I use this model without any issues

    I live in smaller town and older house. Lights dim and flicker with larger appliances are turn on and off. in addition, we have pretty good thunder storms here so I prefer to run a UPS for peace of mind plus the machine can run up to 5-minutes off the battery so I have time to shut her down.

    Most UPS shut-off around 20% battery capacity to prevent full-discharge.  It should last for 5-10 minutes at load.  Most have USB and software to signal line power interruption and possibly auto shutdown for computer/server if power is not restored with "n" minutes.  The better UPS are typically designed for commercial-use and have more battery runtime capacity.  We need the load capacity, but not necessarily the longer runtime.
     
    In Hawaii, we have frequent dips and blackouts.  Infrequent brownouts so just need voltage regulation and UPS.  Normally, I wait a couple minutes before I initiate a manual shutdown.
     
    Did a search on CDW and ignore the Tripplites...

    Cyberpower has 2 models not easily found on their website, but they are rated at 1050w.  Cheapest APC is SMT1500 at 1000w.  The Eaton 5SC 1500 would work, too.  Find somewhere that has a good shipping rate and reputation.  I get free expedited shipping with BB, unlike Prime and no hassle returns.

    Hybrid kit shouldn't affect power.  The fans and pump is a relatively small load.  Try running 3dmark and check your peak load.  It should be close to your worst case scenario without overloading.  710w is still safe.  I don't like to run anything over 95% capacity.  Electrical outlet circuits should be kept to 75% load.  15a circuit breaker should run no more than 12 amp max continuous load.  We're running close to 8 amps with OC'd 8-core, SLI, multi-monitor, and surround speakers.

    Just tried Rise of the Tomb Raider and while the thing wasn't beeping, it stayed at around 730 W while playing.  It is rather comical to play this game on a 165 Hz monitor and having to have to enable Vsync to keep it from tearing.  Enabling the power hungry and fps destroying SMAA x2 did the job getting the fps down to around 130.  :-)
     
    Still not sure if I should go balls to the wall and spend 460 dollars on the SMT 1500 or try the more consumer orientated APC 1500 for 180 bucks, or even that Cyberpower one.  Then again, seeing how much money is hooked up to that thing, it probably deserves the better one.  Decisions decisions.
     
    Angry Ace, when you say you have no issues with the CyberPower 1500, have you tried any benchmarking like Time Spy?  Do you overclock your cards?

    Frankly I don't get it all this, from a better word, skimping on proper UPS. You haven't blinked on buying 2 GPUs for 800$ + rest of the system and now there is a problem with getting proper UPS which will handle all that load at good efficiency because its too expensive... Between choice consumer and server always get server. All consumer UPS HATE active PFC on PSUs. Its a fact of life since first version of APC backup series hit the market - APC themselves say this, but very quietly... only with a  shall we say trusted support guy. 
     
    1050W UPS with 1200W PSU that's asking for trouble. OCP will have field day when efficiency goes down. It doesn't have to be new, new. Refurb with new batteries is good option. I've used(ing) tons of APC2200 VA (IIRC 1600W give or take) and these units go for circa 250-300$ where I live (not US and its including freaking VAT). After 5 years or so I get another one because its not worth to buy certified batteries while whole units is cheaper. There is no substitute for proper UPS. Especially when you know there are regular blackouts. My 3000VA Cyberpower is a rackmount tower but not in rack, its just easier to handle that way. It was the only new UPS I got in recent memory rest is sturdy SmartAPC2200 (not the newest one with these sleek front face and LCD but older models some even without USB just COM). Working first class.

    I've never used a UPS on any of my rigs. All have been fine without one. If you want/need a UPS for your system that is fine.

    Based on your figures and some room for growth, a 900w unit should be "good enough."  There's a lot of choices in the $200-$350 range.  I mentioned the APC Smart UPS SMT1500 T Series since it's the largest 15amp unit that has a 1000w rating.  All "1500va" units are the max size for 15amp house circuits.  If you can feel the heat on the circuit breaker with your hand close to it, then it would be a good idea to double check everything that's plugged in.
